What is 20 Mesh Silica Sand?
Silica sand, also known as quartz sand, is a granular material primarily composed of silicon dioxide (SiO2). Its value in industry stems from its hardness, chemical stability, and thermal resistance. The ‘mesh’ designation refers to the particle size, determined by the number of openings per linear inch in a sieve. 20 mesh silica sand indicates that the sand particles are sized such that they pass through a sieve with 20 openings per inch but are retained on a sieve with a higher mesh count (meaning smaller openings). This typically corresponds to a particle diameter between approximately 0.841 mm and 1.000 mm.
This specific particle size places 20 mesh silica sand in the medium-coarse category. It is coarser than fine filtration sands but finer than gravel or coarse aggregates. This intermediate size grants it unique properties highly sought after in industrial applications. For instance, in filtration systems, it allows for a good balance between trapping smaller particles and maintaining a reasonably high flow rate, preventing system clogs more effectively than finer sands. In abrasive applications, it provides effective surface cleaning without being overly aggressive on delicate substrates. This makes it a versatile choice for various industrial operations in Bangor.
